Sean will be replacing Real Housewives of DC star Michaele Salahi, 45, who got kicked off the show for not having an addiction. Michaele’s husband Tareq Salahi has admitted his wife has no substance abuse issues but claims she needed treatment to deal with the stress of managing her multiple sclerosis which she claims to have had for over 20 years. Which makes us wonder, if she’s had the MS for 20+ years, why would she need Celebrity Rehab with dealing with it now?

As suspected, the MS story seems to be a crock with a source telling RadarOnline this week that Dr. Drew Pinsky ran a number of extensive neurological tests, which all came out negative for MS or any other neurological issues.

There was also a rumor floating around this week that professional famewhoreHeidi Montag would be joining the show, but that report is false.

And finally, the ABC network will be airing a 20/20 special tonight titled “The Phenomenon of Reality Television.” The special promises an in depth look at reality stars who are famous for being famous including the Bravo Housewives, while also examining those who are cashing in.

The special will examine why things often turn so nasty on the Bravo Housewives series. Part of the press release states “20/20 talks to Kyle Richards of the Beverley Hills show about the ugly showdown with her sister Kim, and to Michaele and Tareq Salahis (best known for gate crashing the White House), who say why they believe the other DC Housewives turned against them.”

As for Bethenny, her segment will be more on the cashing in part. She tells “20/20″ that being the focus her own show, “Bethenny Ever After,” has both its rewards and challenges. “Do I speak inappropriately? Absolutely. Is it at my own expense and no one else’s? Absolutely. I don’t need to rip anybody else. I rip myself more than anyone else,” reveals Bethenny.

The special airs at 10/9c. Feel free to discuss the latest news plus the 20/20 special below!
